#
# This file has some examples for creating a MIN_CONFIG.
# (A .config file that is the minimum for a machine to boot, or
#  to boot and make a network connection.)
#
# A MIN_CONFIG is very useful as it is the minimum configuration
# needed to boot a given machine. You can debug someone else's
# .config by only setting the configs in your MIN_CONFIG. The closer
# your MIN_CONFIG is to the true minimum set of configs needed to
# boot your machine, the closer the config you test with will be
# to the users config that had the failure.
#
# The make_min_config test allows you to create a MIN_CONFIG that
# is truly the minimum set of configs needed to boot a box.
#
# In this example, the final config will reside in
# ${CONFIG_DIR}/config-new-min and ${CONFIG_DIR}/config-new-min-net.
# Just move one to the location you have set for MIN_CONFIG.
#
# The first test creates a MIN_CONFIG that will be the minimum
# configuration to boot ${MACHINE} and be able to ssh to it.
#
# The second test creates a MIN_CONFIG that will only boot
# the target and most likely will not let you ssh to it. (Notice
# how the second test uses the first test's result to continue with.
# This is because the second test config is a subset of the first).
#
# The ${CONFIG_DIR}/config-skip (and -net) will hold the configs
# that ktest.pl found would not boot the target without them set.
# The config-new-min holds configs that ktest.pl could not test
# directly because another config that was needed to boot the box
# selected them. Sometimes it is possible that this file will hold
# the true minimum configuration. You can test to see if this is
# the case by running the boot test with BOOT_TYPE = allnoconfig and
# setting setting the MIN_CONFIG to ${CONFIG_DIR}/config-skip. If the
# machine still boots, then you can use the config-skip as your MIN_CONFIG.
#
# These tests can run for several hours (and perhaps days).
# It's OK to kill the test with a Ctrl^C. By restarting without
# modifying this config, ktest.pl will notice that the config-new-min(-net)
# exists, and will use that instead as the starting point.
# The USE_OUTPUT_MIN_CONFIG is set to 1 to keep ktest.pl from asking
# you if you want to use the OUTPUT_MIN_CONFIG as the starting point.
# By using the OUTPUT_MIN_CONFIG as the starting point will allow ktest.pl to
# start almost where it left off.
